Seth Berger
Head Coach

Seth Berger is in his 11th season as Head Coach at Westtown. Prior to that, he was an assistant coach at Westtown for two years. In his first eight years, Westtown had a 203-75 record, winning Friends Schools League championships in 2012, and consecutively from 2014 to 2017. The school’s only prior championship was won in 1986. Under Coach Berger, the team was also runner-up in the PAISAA championships these years and won the state title in 2016 and 2017. In addition, Westtown has won numerous holiday tournaments during Coach Berger’s tenure, including three championships at the Trenton Catholic holiday event, and two championships at the prestigious Bullis School tournament.

Coach Berger, while often soft-spoken in practice, believes strongly that success is in the details, and he works to help his players maximize their abilities, whether they are moving on to play D1, D2, D3, or intramural ball in college. He has coached two NBA players, one McDonald’s All-American, and one NCAA Champion. His love of the game is reflected in his commitment to his players, and to the fact that he still thinks he could be a backup point guard in the NBA. Seth lives in Malvern with his wife Christelle and their sons Cole ’17, TJ ’20, and Quin ’22.
